I don't think the material used to build your surfboard is a large percentage of your effect on the environment. Go for the low hanging fruit first. Unless it makes you feel good to have a "green" surfboard, I don't think that's the most effective place to spend your money to save the environment.

Dr M you've no doubt been in the land of the Pharisees too long,
maybe u smoked something green or maybe it's a contact high from your green-mantra-chanting neighbors, maybe it's time to liberate a few hundred pounds more CO2,
take a jet out of the formerly golden state and check in to reality,
catch some waves while you're at it.
Kiting is greener than auto or powerboat racing, so pat yourself on the back if you need to, take care of your gear and keep on flying that ragged out kite, ride a plank of wood, no resin, dude, no foam, man, be kind, be green, be happy.
But no, it's not all that green, is it?

People still don't realize it has less overall environmental impact to keep driving a 10 year old van or truck than to buy a new prius and put 150000 miles on it, it's a crazy world, just try to enjoy it and don't be taken in too often by fads and fashion.

you'll probably never make kiting green. unless you'll start making your kites out of hemp growing in your back yard.

but you can make it greener at least.

first, stop buying new gear every year. yearly improvements of the kiteboarding gear are so marginal you can hardly even call an improvements. it is more like corrections of the flaws of the previous editions (well kite brand would call it generations of course). all you really get is different graphic design.

second, kite at home spot or not too far from it. tourism is one of the biggest cause of pollution in the world. and contrary to the wide spread myth of positive influence of tourism to a third world economies there are opinions that the one-sided tourism addiction in economy is dangerous and not sustainable.

and of course you can also carpooling more and use more economical cars for getting to spot.

Sure we can push for green manufacturing, but we are a teeny tiny little industry. Its the auto and energy sectors that need be changed.

Lots of issues. As pointed out, people are clueless as to what actually constitutes green, where dudes and dudettes in their fancy new hybrids will thumb their egotistical noses at the old redneck in his 92 clunker and yet. He's the green one.

Dont litter, in fact pick it up, buy less gear less often, Carpool to the spot, Nothing wrong with these suggestions and no they will not save the world, but they help teach our kids that every bit counts and that its everyones problem and that in the end we are the ones that are gonna have to deal with it.

Im all for a green surfboard. Looking into a Lib Tech for the next one..... once I break one of the ones I have

let's not spill the baby with the bathtub - couple of things here. Nobody suggested that we have to go all the way rather being AWARE of the impact how OUR stuff is been made, distributed and disposed. If you don't care - well, sad, but so be it - and if you care, no need to call these people names and imply an 'extreme' agenda.
Sure, the industry is small. But let alone we don't associate us with this industry alone. Most of us are in related water sports as well (kayak, surfing ...). If we don't ask the industry, they won't supply us. It's that simple. 10 years ago nobody gave a rat's ass about a hybrid now they sold like hot cupcakes.

On a personal note: I like living in CA. Not a perfect state (but show me one which is) but a think tank when it comes to NEW stuff,with a different approach. Lots of water sports and especially surfing have deep roots here. So I would bet that the next big (green?) thing will come from us?

So, I said in the OP: Just wondering where's everybody's mind on this?
